III. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Now referring primarily to FIG. 1, which illustrates a method of using a particular embodiment of an inventive connector (1) which couples to an outlet conduit (2) to decrease an outlet conduit passageway pressure differential (3) between outlet conduit opposing first and second ends (4)(5), whereby the connector (1) includes a mixing chamber (6) having a first inlet port (7) in fluidic communication with a connector first open end (8) and the mixing chamber (6); an outlet port (9) in fluidic communication with the mixing chamber (6) and a connector second open end (10); and a second inlet port (11) in fluidic communication with the connector second open end (10) and the mixing chamber (6).

The method includes coupling a first inlet conduit (12) to the connector first open end (8) to fluidicly couple a first inlet conduit passageway (13) with the first inlet port (7), coupling the outlet conduit (2) to the connector second open end (10) to fluidicly couple an outlet conduit passageway (14) with the outlet port (9), and coupling a second inlet conduit (15) to the connector second open end (10) to fluidicly couple a second inlet conduit passageway (16) with the second inlet port (11).

As to particular embodiments, the method further includes generating a flow of a first fluid (17) in a first fluid flow path (18) defined by the first inlet conduit passageway (13), the first inlet port (7), the mixing chamber (6), the outlet port (9), and the outlet conduit passageway (14) (for example, from the first inlet conduit passageway (13) toward the outlet conduit passageway (14)); and generating a flow of a second fluid (19) in a second fluid flow path (20) defined by the second inlet conduit passageway (16), the second inlet port (11), and the mixing chamber (6) (for example, from the second inlet conduit passageway (16) toward the mixing chamber (6)). Within the mixing chamber (6), the second fluid (19) mixes with the first fluid (17) to decrease the outlet conduit passageway pressure differential (3) between the outlet conduit opposing first and second ends (4)(5).

Now referring primarily to FIG. 2 through FIG. 11, the connector (1) includes a mixing chamber (6) which, as to particular embodiments, can be defined by a connector internal surface (21) between connector first and second open ends (8)(10).

Now referring primarily to FIG. 3 and FIG. 5, the mixing chamber (6) includes a first inlet port (7) in fluidic communication with the connector first open end (8) and the mixing chamber (6). Accordingly, a first fluid (17) can ingress into the mixing chamber (6) from the connector first open end (8) by flowing through the first inlet port (7), whereby as to particular embodiments, the first fluid (17) can be a liquid.

Now referring primarily to FIG. 5 and FIG. 6, the mixing chamber (6) further includes an outlet port (9) in fluidic communication with the mixing chamber (6) and the connector second open end (10). Accordingly, the first fluid (17) can egress from the mixing chamber (6) toward the connector second open end (0) by flowing through the outlet port (9).

Correspondingly, a first fluid flow path (18) can be defined by the connector first open end (8), the first inlet port (7), the mixing chamber (6), the outlet port (9), and the connector second open end (10), whereby as to particular embodiments, the first fluid (17) can flow from the connector first open end (8), through the mixing chamber (6), and toward the connector second open end (10) (as shown in the example of FIG. 12).

Now referring primarily to FIG. 2, FIG. 16, and FIG. 17, the connector first open end (8) can be configured to couple to a first inlet conduit (12) to fluidicly couple a first inlet conduit passageway (13) with the first inlet port (7) and the connector second open end (10) can be configured to couple to an outlet conduit (2) to fluidicly couple an outlet conduit passageway (14) with the outlet port (9).

As but one illustrative example, the first inlet conduit (12) and the outlet conduit (2) can be received within the corresponding connector first and second open ends (8)(10) to sealably engage the first inlet conduit (12) and the outlet conduit (2) with the corresponding connector first and second open ends (8)(10) and fluidicly couple the first inlet conduit passageway (13) and the outlet conduit passageway (14) with the corresponding first inlet port (7) and outlet port (9).

As another illustrative example, the first inlet conduit (12) and the outlet conduit (2) can be disposed around the corresponding connector first and second open ends (8)(10) to sealably engage the first inlet conduit (12) and the outlet conduit (2) with the corresponding connector first and second open ends (8)(10) and fluidicly couple the first inlet conduit passageway (13) and the outlet conduit passageway (14) with the corresponding first inlet port (7) and outlet port (9).

Now referring primarily to FIG. 16 and FIG. 17, upon coupling of the first inlet conduit (12) and the outlet conduit (2) to the corresponding connector first and second open ends (8)(10), the first fluid flow path (18) can be defined by the first inlet conduit passageway (13), the first inlet port (7), the mixing chamber (6), the outlet port (9), and the outlet conduit passageway (14), whereby as to particular embodiments, the first fluid (17) can flow from the first inlet conduit passageway (13), through the mixing chamber (6), and toward the outlet conduit passageway (14).

Now referring primarily to FIG. 1, the outlet conduit (2) has outlet conduit opposing first and second ends (4)(5), in between which the outlet conduit passageway (14) is disposed. The outlet conduit first end (4) can couple to the connector second open end (10) and the outlet conduit second end (5) can couple to a collection reservoir (22) to fluidicly couple the mixing chamber (6) with the collection reservoir (22) via the outlet conduit passageway (14). Subsequently, as to particular embodiments, the first fluid (17) can flow in the first fluid flow path (18) from the first inlet conduit passageway (13), through the mixing chamber (6) and the outlet conduit passageway (14), and into the collection reservoir (22), generating a closed fluid flow path between the first inlet conduit passageway (13) and the collection reservoir (22).

For the purposes of the present invention, the term “closed fluid flow path” means a fluid flow path in which mass does not transfer into or out of.

Following, as the first fluid (17) is collected within the collection reservoir (22), an outlet conduit passageway pressure differential (3) between the outlet conduit opposing first and second ends (4)(5) can be generated. As such, a greater pressure (or positive pressure) can be generated within the outlet conduit passageway (14) proximate the outlet conduit second end (5) relative to the outlet conduit first end (4), whereby the greater pressure can inhibit, either partially or completely, the flow of the first fluid (17) into the collection reservoir (22).

As but one illustrative example, the first inlet conduit (12) can be configured as a catheter (23) having a catheter first end coupled to a bladder of a user (not shown) and a catheter second end coupled to the connector first open end (8), fluidicly coupling the bladder with the mixing chamber (6) via a catheter passageway (25) between the catheter first end and the catheter second ends. The outlet conduit (2) can have an outlet conduit first end (4) coupled to the connector second open end (10) and an outlet conduit second end (5) coupled to a collection reservoir (22) configured as a urine drainage bag (26), fluidicly coupling the mixing chamber (6) with the urine drainage bag (26) via the outlet conduit passageway (14). Accordingly, the first fluid (17), which can be urine, can flow in the closed fluid flow path from the bladder to the urine drainage bag (26). However, upon collection of an amount of urine within the urine drainage bag (26), a greater pressure can be generated within the outlet conduit passageway (14) proximate the outlet conduit second end (5) relative to the outlet conduit first end (4). In addition to potentially inhibiting, either partially or completely, the flow of urine from the bladder to the urine drainage bag (26), the greater pressure may also cause discomfort or pain to the user.

Therefore, the mixing chamber (6) further includes a second inlet port (11) in fluidic communication with the connector second open end (10) and the mixing chamber (6). Accordingly, a second fluid (19) can ingress into the mixing chamber (6) from the connector second open end (10) by flowing through the second inlet port (11), whereby as to particular embodiments, the second fluid (19) can be a gas.

Correspondingly, a second fluid flow path (20) can be defined by the connector second open end (10), the second inlet port (11), and the mixing chamber (6), whereby as to particular embodiments, the second fluid (19) can flow from the connector second open end (10) toward the mixing chamber (6).

Now referring primarily to FIG. 2, FIG. 16, and FIG. 17, the connector second open end (10) can further be configured to couple to a second inlet conduit (15) to fluidicly couple a second inlet conduit passageway (16) with the second inlet port (11).

Again referring primarily to FIG. 2, FIG. 16, and FIG. 17, upon coupling of the second inlet conduit (15) to the connector second open end (10), the second fluid flow path (20) can be defined by the second inlet conduit passageway (16), the second inlet port (11), and the mixing chamber (6), whereby as to particular embodiments, the second fluid (19) can flow from the second inlet conduit passageway (16) toward the mixing chamber (6).

Now referring primarily to FIG. 1, the second inlet conduit (15) has second inlet conduit opposing first and second ends (27)(28), in between which the second inlet conduit passageway (16) is disposed. The second inlet conduit first end (27) can couple to the connector second open end (10) and the second inlet conduit second end (28) can couple to the collection reservoir (22) to fluidicly couple the collection reservoir (22) to the mixing chamber (6) via the second inlet conduit passageway (16). Subsequently, as to particular embodiments, the second fluid (19) can flow in the second fluid flow path (20) from the collection reservoir (22), through the second inlet conduit passageway (16), and into the mixing chamber (6), adding to the closed fluid flow path between the first inlet conduit passageway (13) and the collection reservoir (22).

Following, as the first fluid (17) is collected within the collection reservoir (22) and an outlet conduit passageway pressure differential (3) between the outlet conduit opposing first and second ends (4)(5) is generated, as to particular embodiments, the second fluid (19) can flow in the second fluid flow path (20) from the second inlet conduit passageway (16) toward the mixing chamber (6). Within the mixing chamber (6), the second fluid (19) mixes with the first fluid (17) to decrease the outlet conduit passageway pressure differential (3) between the outlet conduit opposing first and second ends (4)(5).

Regarding the illustrative example whereby the first inlet conduit (12) is configured as a catheter (23) coupled between a bladder of a user and the connector first open end (8), and the outlet conduit (2) couples between the connector second end (10) and a urine drainage bag (26), urine can flow in the closed fluid flow path from the bladder to the urine drainage bag (26). Upon collection of an amount of urine within the urine drainage bag (26), the second fluid (19), such as gas from a headspace of the urine drainage bag (26), can flow in the second fluid flow path (20) from the collection reservoir (22), through the second inlet conduit passageway (16), and into the mixing chamber (6), in which the second fluid (19) can mix with the urine to decrease the outlet conduit passageway pressure differential (3) between the outlet conduit opposing first and second ends (4)(5). Hence, upon collection of the urine within the urine drainage bag (26), a significant outlet conduit passageway pressure differential (3) may not be generated and, consequently, the flow of urine from the bladder to the urine drainage bag (26) may not be inhibited.

As to particular embodiments, when flowing in the second fluid flow path (20), the second fluid (19) can urge the first fluid (17) through the outlet port (9) and into the outlet conduit passageway (14), thereby facilitating flow of the first fluid (17) in the first fluid flow path (18).

Now referring primarily to FIG. 12A and FIG. 12B, the connector (1) can, but need not necessarily, further include a first valve (29) disposed within the first fluid flow path (18) to regulate flow of the first fluid (17). As to particular embodiments, the first valve (29) can be a unidirectional first valve (29) configured to allow a first directional flow of the first fluid (17) from the connector first open end (8) toward the connector second open end (10). Correspondingly, the unidirectional first valve (29) interrupts a second directional flow of the first fluid (17) from the connector second open end (10) toward the connector first open end (8).

Thus, upon coupling of the first inlet conduit (12) and the outlet conduit (2) to the corresponding connector first and second open ends (8)(10), the first fluid flow path (18), defined by the first inlet conduit passageway (13), the first inlet port (7), the mixing chamber (6), the outlet port (9), and the outlet conduit passageway (14), can be a unidirectional fluid flow path, whereby the first fluid (17) flows only from the first inlet conduit passageway (13) toward the outlet conduit passageway (14).

The unidirectional first valve (29) can have any type of valve configuration capable of regulating flow of the first fluid (17) as described herein and, without limitation to the breadth of the foregoing, can include as illustrative examples: a duckbill valve, a flapper valve, an umbrella valve, a spring-loaded valve, or any of a numerous and wide variety of valve configurations as would be known to one of ordinary skill in the art as capable of unidirectionally regulating a fluid flow.

Now referring primarily to FIG. 19 through FIG. 21, the connector (1) can, but need not necessarily, further include a second valve (30) disposed within the second fluid flow path (20) to regulate flow of the second fluid (19). As to particular embodiments, the second valve (30) can be a unidirectional second valve (30) configured to allow a first directional flow of the second fluid (19) from the connector second open end (10) toward the mixing chamber (6). Correspondingly, the unidirectional second valve (30) interrupts a second directional flow of the second fluid (19) from the mixing chamber (6) toward the connector second open end (10).

Thus, upon coupling of the second inlet conduit (15) to the connector second open end (10), the second fluid flow path (20), defined by the second inlet conduit passageway (16), the second inlet port (11), and the mixing chamber (6), can be a unidirectional fluid flow path, whereby the second fluid (30) flows only from the second inlet conduit passageway (16) toward the mixing chamber (6).

The unidirectional second valve (30) can have any type of valve configuration capable of regulating flow of the second fluid (19) as described herein and, without limitation to the breadth of the foregoing, can include as illustrative examples: a duckbill valve, a flapper valve, an umbrella valve, a spring-loaded valve, or any of a numerous and wide variety of valve configurations as would be known to one of ordinary skill in the art as capable of unidirectionally regulating a fluid flow.

As to particular embodiments, the unidirectional second valve (30) can be coupled or connected to the connector internal surface (21) to dispose the unidirectional second valve (30) within the second fluid flow path (20) (not shown).

As to other particular embodiments, the unidirectional second valve (30) can be disposed within the second inlet conduit passageway (16) to dispose the unidirectional second valve (30) within the second fluid flow path (20) (as shown in the examples of the Figures).

As to particular embodiments, the outlet conduit (2) having the outlet conduit passageway (14) can be discrete from the second inlet conduit (15) having the second inlet conduit passageway (16) (not shown).

Now referring primarily to FIG. 2, FIG. 16, FIG. 17, and FIG. 18 through FIG. 21, as to other particular embodiments, the outlet conduit (2) and the second inlet conduit (15) can be combined into a one-piece tubular construct (31) including both the outlet conduit passageway (14) and the second inlet conduit passageway (16).

The one-piece tubular construct (31) can have one-piece tubular construct opposing external and internal surfaces (32)(33) disposed between one-piece tubular construct opposing first and second ends (34)(35), whereby the one-piece tubular construct internal surface (33) can define a discrete outlet conduit passageway (14) and a discrete second inlet conduit passageway (16), both of which communicate between the one-piece tubular construct opposing first and second ends (34)(35).

As to particular embodiments, the outlet conduit passageway (14) and the second inlet conduit passageway (16) can dispose in laterally adjacent relation to one another between the one-piece tubular conduit opposing first and second ends (34)(35) (as shown in the examples of the Figures).

As to other particular embodiments, the outlet conduit passageway (14) and the second inlet conduit passageway (16) can dispose in concentric relation to one another between the one-piece tubular conduit opposing first and second ends (34)(35) (not shown).

Now referring primarily to FIG. 1, which illustrates a method of using another particular embodiment of an inventive connector (1) for sensing a parameter of a first fluid (17) flowing in a first fluid flow path (18) through a connector passageway (36), whereby the connector (1) includes a connector internal surface (21) defining a connector passageway (36) which communicates between connector first and second open ends (8)(10); and a sensor module (37) operatively coupled to the connector passageway (36). The method includes generating a flow of the first fluid (17) in the first fluid flow path (18) through the connector passageway (36), and sensing the parameter of the first fluid (17) flowing in the first fluid flow path (18) through the connector passageway (36).

Now referring primarily to FIG. 3, the connector (1) includes a connector internal surface (21) defining a connector passageway (36) which communicates between connector first and second open ends (8)(10).

Correspondingly, a first fluid flow path (18) can be defined by the connector first open end (8), the connector passageway (36), and the connector second open end (10), whereby as to particular embodiments, the first fluid (17) flows from the connector first open end (8), through the connector passageway (36), and toward the connector second open end (10).

Now referring primarily to FIG. 2, FIG. 16, and FIG. 17, the connector first open end (8) can be configured to couple to a first inlet conduit (12) to fluidicly couple a first inlet conduit passageway (13) with the connector passageway (36), and the connector second open end (10) can be configured to couple to an outlet conduit (2) to fluidicly couple an outlet conduit passageway (14) with the connector passageway (36).

As but one illustrative example, the first inlet conduit (12) and the outlet conduit (2) can be received within the corresponding connector first and second open ends (8)(10) to sealably engage the first inlet conduit (12) and the outlet conduit (2) with the corresponding connector first and second open ends (8)(10) and fluidicly couple the first inlet conduit passageway (13) and the outlet conduit passageway (14) with the connector passageway (36).

As another illustrative example, the first inlet conduit (12) and the outlet conduit (2) can be disposed around the corresponding connector first and second open ends (8)(10) to sealably engage the first inlet conduit (12) and the outlet conduit (2) with the corresponding connector first and second open ends (8)(10) and fluidicly couple the first inlet conduit passageway (13) and the outlet conduit passageway (14) with the connector passageway (36).

Now referring primarily to FIG. 16 and FIG. 17, upon coupling of the first inlet conduit (14) and the outlet conduit (2) to the corresponding connector first and second open ends (8)(10), the first fluid flow path (18) can be defined by the first inlet conduit passageway (13), the connector passageway (36), and the outlet conduit passageway (14).

Now referring primarily to FIG. 12A and FIG. 12B, the connector (1) can, but need not necessarily, further include a first valve (29) disposed within the first fluid flow path (18) to regulate flow of the first fluid (17). As to particular embodiments, the first valve (29) can be a unidirectional first valve (29) configured to allow a first directional flow of the first fluid (17) from the connector first open end (8) toward the connector second open end (10). Correspondingly, the unidirectional first valve (29) interrupts a second directional flow of the first fluid (17) from the connector second open end (10) toward the connector first open end (8).

Thus, upon coupling of the first inlet conduit (12) and the outlet conduit (2) to the corresponding connector first and second open ends (8)(10), the first fluid flow path (18), defined by the first inlet conduit passageway (13), the connector passageway (36), and the outlet conduit passageway (14), can be a unidirectional fluid flow path, whereby the first fluid (17) flows only from the first inlet conduit passageway (13) toward the outlet conduit passageway (14).

The unidirectional first valve (29) can have any type of valve configuration capable of regulating flow of the first fluid (17) as described herein and, without limitation to the breadth of the foregoing, can include as illustrative examples: a duckbill valve, a flapper valve, an umbrella valve, a spring-loaded valve, or any of a numerous and wide variety of valve configurations as would be known to one of ordinary skill in the art as capable of unidirectionally regulating a fluid flow.

Now referring primarily to FIG. 22, the connector (1) further includes a sensor module (37) operatively coupled to the connector passageway (36) to sense a parameter of a first fluid (17) flowing in a first fluid flow path (18) through the connector passageway (36).

Again referring primarily to FIG. 22, the sensor module (37) can include one or more sensors (38) which each generate a sensor signal (39). The sensor module (37) can further include a microcontroller (40) configured to receive, process, and transform each sensor signal (39).

The microcontroller (40) can take the form of a small computer on one or more integrated circuits, whereby the microcontroller (40) can include at least one processor (41) which operatively controls the function of a variety of modules (42) stored as computer program code (43) in a programmable memory element (44), whereby each module (42) functions to provide a response related to the sensor signal (39) received by the microcontroller (40). A bus can operably couple components of the microcontroller (40), including without limitation, the processor (41) and the programmable memory element (44).

The microcontroller (40) can be a conventional microcontroller (40). As an illustrative example, a microcontroller (40) suitable for use with embodiments of the connector (1) can be obtained from Microchip Technology Inc., 2355 West Chandler Boulevard, Chandler, Ariz. 85224, USA, for example Part Numbers PIC18F4620-I/PT, PIC18LF14K22, or PIC18LF15K22. However, the invention need not be so limited, as any of a numerous and wide variety of similar or equivalent components can be suitable as a microcontroller (40) programmable to perform the functions of the connector (1) as described or shown herein.

The processor (41) can include one central-processing unit (CPU), a plurality of processors which operate in parallel to process digital information, a digital signal processor (DSP) plus a host processor, or the like, or other conventional processors (41) as would be known to one of ordinary skill in the art.

The bus can include any bus configuration having any of a wide variety of bus architectures.

The programmable memory element (44) can be a read only memory (ROM) or a random access memory (RAM), or both, or other conventional memory elements (44) as would be known to one of ordinary skill in the art.

Again referring primarily to FIG. 22, the one or more sensors (38) can include any of a wide variety of sensors (38) which can sense various parameters of the first fluid (17) flowing in the first fluid flow path (18) through the connector passageway (36). As non-limiting examples, the sensed parameters can include fluid flow rate (45), fluid volume (46), fluid temperature (47), fluid pH (48), fluid conductivity (49), fluid turbidity (50), amount of blood in fluid (51), amount of protein in fluid (52), amount of dissolved gas in fluid (53), or the like, or combinations thereof, or any desired parameter of the first fluid (17) flowing in the first fluid flow path (18) through the connector passageway (36).

As to particular embodiments, the sensor (38) can be a fluid flow rate sensor (54) which can send a sensor signal (39) to a fluid flow rate calculation module (55) within the microcontroller (40). As to particular embodiments, the fluid flow rate sensor (54) can have a resistive element configured to maintain a constant temperature. When the first fluid (17) flowing in the first fluid flow path (18) through the connector passageway (36) has a fluid temperature lesser than the temperature which the resistive element is configured to maintain, an amount of heat transfers from the resistive element to the first fluid (17), thereby lessening the temperature of the resistive element below the temperature which the resistive element is configured to maintain. Accordingly, an amount of current is generated to increase the temperature of the resistive element toward the temperature which the resistive element is configured to maintain, whereby the amount of current required to increase the temperature can be related to the fluid flow rate of the first fluid (17) flowing in the first fluid flow path (18) through the connector passageway (36).

As can be easily understood from the foregoing, the basic concepts of the present invention may be embodied in a variety of ways. The invention involves numerous and varied embodiments of a connector system and methods for making and using such a connector system, including the best mode.

As such, the particular embodiments or elements of the invention disclosed by the description or shown in the figures or tables accompanying this application are not intended to be limiting, but rather exemplary of the numerous and varied embodiments generically encompassed by the invention or equivalents encompassed with respect to any particular element thereof. In addition, the specific description of a single embodiment or element of the invention may not explicitly describe all embodiments or elements possible; many alternatives are implicitly disclosed by the description and figures.

It should be understood that each element of an apparatus or each step of a method may be described by an apparatus term or method term. Such terms can be substituted where desired to make explicit the implicitly broad coverage to which this invention is entitled. As but one example, it should be understood that all steps of a method may be disclosed as an action, a means for taking that action, or as an element which causes that action. Similarly, each element of an apparatus may be disclosed as the physical element or the action which that physical element facilitates. As but one example, the disclosure of a “flow” should be understood to encompass disclosure of the act of “flowing”—whether explicitly discussed or not—and, conversely, were there effectively disclosure of the act of “flowing”, such a disclosure should be understood to encompass disclosure of a “flow” and even a “means for flowing.” Such alternative terms for each element or step are to be understood to be explicitly included in the description.

In addition, as to each term used it should be understood that unless its utilization in this application is inconsistent with such interpretation, common dictionary definitions should be understood to be included in the description for each term as contained in the Random House Webster's Unabridged Dictionary, second edition, each definition hereby incorporated by reference.

All numeric values herein are assumed to be modified by the term “about”, whether or not explicitly indicated. For the purposes of the present invention, ranges may be expressed as from “about” one particular value to “about” another particular value. When such a range is expressed, another embodiment includes from the one particular value to the other particular value. The recitation of numerical ranges by endpoints includes all the numeric values subsumed within that range. A numerical range of one to five includes for example the numeric values 1, 1.5, 2, 2.75, 3, 3.80, 4, 5, and so forth. It will be further understood that the endpoints of each of the ranges are significant both in relation to the other endpoint, and independently of the other endpoint. When a value is expressed as an approximation by use of the antecedent “about,” it will be understood that the particular value forms another embodiment. The term “about” generally refers to a range of numeric values that one of skill in the art would consider equivalent to the recited numeric value or having the same function or result. Similarly, the antecedent “substantially” means largely, but not wholly, the same form, manner or degree and the particular element will have a range of configurations as a person of ordinary skill in the art would consider as having the same function or result. When a particular element is expressed as an approximation by use of the antecedent “substantially,” it will be understood that the particular element forms another embodiment.

Moreover, for the purposes of the present invention, the term “a” or “an” entity refers to one or more of that entity unless otherwise limited. As such, the terms “a” or “an”, “one or more” and “at least one” can be used interchangeably herein.

Thus, the applicant(s) should be understood to claim at least: i) each of the connector systems herein disclosed and described, ii) the related methods disclosed and described, iii) similar, equivalent, and even implicit variations of each of these devices and methods, iv) those alternative embodiments which accomplish each of the functions shown, disclosed, or described, v) those alternative designs and methods which accomplish each of the functions shown as are implicit to accomplish that which is disclosed and described, vi) each feature, component, and step shown as separate and independent inventions, vii) the applications enhanced by the various systems or components disclosed, viii) the resulting products produced by such systems or components, ix) methods and apparatuses substantially as described hereinbefore and with reference to any of the accompanying examples, x) the various combinations and permutations of each of the previous elements disclosed.
